N.H. Rev. Stat. § 416-A:6
No policy or contract of title insurance shall be written unless and until the title insurance company has caused to be conducted a reasonable examination of the title and has caused to be made a determination of insurability of title in accordance with sound underwriting practices for title insurance companies. Evidence thereof shall be preserved and retained in the files of the title insurance company or its agent or its approved attorney for a period of not less than 20 years after the policy or contract of title insurance has been issued. In lieu of retaining the original copy, the title insurance company or the agent of the title insurance company, may in the regular course of business, establish a system whereby all or part of these writings are recorded, copied, or reproduced by any photographic, photostatic, microfilm, microcard, miniature photographic, or other process which accurately reproduces or forms a durable medium for reproducing the original. This section shall not apply to either a company assuming no primary liability in a contract of reinsurance, or a company acting as a coinsurer if one of the other coinsuring companies has complied with this section.
